A drug that is used to treat serious bleeding could save thousands of lives of mothers giving birth. A world test of the drug found it reduced (降低) the risk of bleeding deaths during childbirth by nearly one third. The study included 20,000 women in 21 countries, mainly in Africa and Asia. The test was carried out by London School of Hygiene and Tropical Medicine. The drug is called tranexamic acid (凝血酸). It is low-cost and researchers said it does not cause serious side effects (副作用) for mothers or babies.

    The drug is used to treat mothers for serious bleeding during childbirth. Postpartum hemorrhage (产后出血) is the main cause of mothers' death around the world, according to the World Health Organization.

    Haleema Shakur is the project director for the test. She said though medical condition is improved in many countries, serious bleeding after childbirth remains a big problem in some parts of the world. “It's one of the biggest killers of mothers. In Africa and Asia, about 10% of women will end up with serious bleeding.” The drug works after a mother gives birth.

    Shakur said the best results were reported when the drug was given to women as soon as possible after childbirth. “The earlier you give it — within the first three hours after giving birth — the better the result is.”

    The next step will be to provide training for doctors and nurses on how to use it and then to find where the drug is needed. During the test, women were given the drug in a hospital. But researchers are looking for easier ways to use the drug so it can be more widely used in small clinics and the countryside.

    Joanna Cole, born on August 11, 1944 in Newark, New Jersey, has been credited to be one of the most popular children's authors of all time. She has written over 250 books and is famous for writing one of the most popular children's book series. She knew as early as 5th grade that she was interested in writing and science. Cole has owed a large part of her passion to one of her elementary school teachers.

    Joanna Cole continued her education by attending the University of Massachusetts and Indiana. She would eventually earn a bachelor's degree in psychology from the City College of New York in 1967; after graduation Cole decided to take some education courses to become a librarian at a Brooklyn elementary school in 1967. Eventually, she would take jobs working for Newsweek, Seesaw book club.

    Cole's passion for writing and science was still alive and well during this time. In 197l she decided to write her first book, Cockroaches. She did some research and discovered there had never been a book written for children about cockroaches. So she thought she would be the first.

    Cole struck gold when she wrote the first Magic School Bus in 1985. The book would go on to be published the following year and quickly became book series and cartoon series due to its success.

    Cole continued to write both non-fiction and fiction books for children. She writes in a way that will hopefully inspire children to think like a scientist. She does this by writing ideas instead of just facts. She also tries to ask questions in her books that require children to think and discover the answers as they read. This creates an engaging experience for children, so it is no wonder why younger readers are hooked on her books.

    Two Chinese sisters have landed a dream trip to Buckingham Palace and the Peppa Pig World theme park in the UK. Lately, their mother helped them express their wish online to meet Queen Elizabeth II, which not only caught millions of social media users' attention but also the attention of the British ambassador (大使) to China.

    Five-year-old twins Mi Ai and Mi Ni, who live in Beijing, appeared in a video on social media platform Weibo last week, where they spoke of their love of British cartoon Peppa Pig and their keen interest to visit the Buckingham Palace. Mi Ni said she and her sister wanted to visit the gardens at Buckingham Palace, just like Peppa Pig and her friends did in the cartoon program.

    The British Ambassador answered their call with her own video, inviting the twins to her house in Beijing. "Hello Mi Ni and Mi Ai," she said. "I'm the British ambassador. I'd like you to come and visit me in my house in Beijing and we can perhaps have tea and cookies in a British style." The twins accepted the ambassador's invitation and joined her for a traditional afternoon tea on Monday, when they ate cake and drew pictures of their favorite characters from Peppa Pig.

    The ambassador has made arrangements for the girls and their parents to tour the UK. They are going to tour the studios where Peppa Pig is made, take a trip to Peppa Pig World in Hampshire and visit Buckingham Palace. The queen has not yet said if she will have time to welcome the girls.

    The Peppa Pig series, introduced in the mid-2000s in China, has become extremely popular among Chinese children and adults. As this year is the Year of the Pig according to Chinese tradition, the country has set to mark the Chinese New Year with a film starring Peppa Pig, where audiences can see a number of Chinese cultural elements (元素).

    Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend's house or in a hotel room, and find it difficult or impossible to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be other reasons.

    According to a new study published in Current Biology, a significant reason is what the scientists call "first night effect". They believe that one side of the brain acts as a "night watch" to warn us about potential dangers. It forces us to stay awake on the first night in a new environments.

    For the study, 35 young volunteers were asked to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.

    According to the researchers, on their first night, the left brain was more active than the right brain and people had a hard time sleeping. However, left-brain activities decreased as days went by, falling even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.

    The findings suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work differently, the balance between them is broken. Thus, the brain can't relax and is sensitive to anything strange in the surroundings, just as it is in the daytime.

    "At some level, the brain is continuing to analyze things, even though you are not aware of the analysis, " US professor Jerome Siegel told Smithsonian

    "If something unusual happens - if a door opens or you hear a key in a lock --you can be alert, even though the intensity of the stimulus (刺激强度) is quite low." More surprisingly, this phenomenon is similar to the way some animals sleep.

    The researchers think that it is the result of evolution (进化), and works to protect us in potentially dangerous environments.

    If you have ever had what you think is "first night effect", researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.

    Jarrett Little was road testing his mountain bike outside of Columbus, Georgia, when his riding partner, Chris Dixon, stopped suddenly. Something in the distance moving among the trees had caught her attention. It turned out to be a sandy-colored five-month-old puppy.

    "He was really thin, ribs showing, and a broken leg," Little told John Parks, a reporter from CBS News. The cyclists fed the friendly pup and shared their water. They also quickly realized that the dog was coming with them, although they had no idea how. They were more than seven miles from downtown and riding bikes. "We couldn't leave him," Little said. "Out there next to the Oxbow Meadows, he was going to become the lunch of an alligator living in the river."

    Suddenly, Little had an idea. He carefully picked up his new friend and slipped the 38-pound dog's hind legs (后肢) into the back pockets of his cycling jacket. Then he hung the dog's front paws over his shoulders.

    "He was injured, so he wasn't trying to fight," Little says. "He was also happy that we were there, touching him, and hadn't taken off on him."

    The group's 30-minute ride into town ended at a bike store, where they got more water and food for the dog. That was when Andrea Shaw, an accountant from Maine in town on business, happened by. The dog made a headed straight for her, licking and "loving on her," says Dixon. Shaw was struck and, after learning what had happened, declared her intentions: "I am keeping this dog."

    Shaw called him Columbo and scheduled an operation on his leg. Today, Columbo is living the high life on a farm with a horse, a pony, a six-year-old boy, to keep him company. As Dixon told John Parks, "He is literally the luckiest dog alive."
